You have a Ryzen. It's not an intel. It doesn't respond, work, act like an intel. So everything you've become accustomed to with Intel thinking, you can throw out the window.
Ryzens work best on Balanced power plan. That's direct from AMD, they even got together with Microsoft and created a Ryzen Master Balanced solution, so either that or Balanced is what's needed to be used. Ryzens have their own performance boosting, PBO, so do not need windows to add to that, in fact it interferes with how Ryzens work, especially concerning idle voltages and core usage.
Yes, you can put fans in front. It may require removal of the front facia to do so.
Utilization is pretty useless. It's not how much of the cpu potential is used, it's how much...
